A greenhouse screen comprising strips (11) of film material that are interconnected by a yarn system of transverse threads (12, 14, 18) and longitudinal threads (13a, 13b; 15; 19) by means of knitting, warp-knitting or weaving process to form a continuous product is disclosed. At least some of the strips (11) comprise a film material in the form of a single- or multilayer polyester film wherein the film contains at least 1.0 wt. -% SiO2 and a maximum of 2.5 wt. -% SiO2, and has a spreading factor (SF) of at least 2 and not more than 8. The greenhouse screen as disclosed herein has a reduced flammability and light scattering properties particularly suited for greenhouse applications.
